These are two Stone Memorial Tablets for King Muryeong, the 25th King of Baekje, and his Queen Consort. The front of the tablet is inscribed with 6 lines of record, each line measuring 5 to 6 centimeters. They coincide with the record of King Muryeong in Samguk Sagi (History of the Three Kingdoms). The back of the memorial tablet is inscribed with a square, which indicates 12 directions, except the west. The Queen's memorial tablet has 13 lines, of which only four lines are filled with inscriptions, each measuring 2.5 to 2.8 centimeters. The back of the tablet is inscribed with maejimun (certificate of ownership of the land). Initially the certificate was inscribed on a stone tablet when King Muryeong was buried, and its back was later used for Queen's memorial tablet when she was buried next to the King. This memorial tablet is considered one of the most valuable relics, enabling the archaeologists to pinpoint the exact attribution of the tombs in the Three Kingdoms Era, as well as to understand the funeral culture of Baekje.
